MOLD FOR GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 405,863, dated June 25,1889.

Serial No. 249,344. (No model.)

To all whom, it may concern:

Be it known that we, RICHARD M. ATWATER and EMIL HEECKNER, both citizensof the United States, and residents of Millville, Cumberland county, NewJersey, have invented certain Improvements in Molds for Glassware, ofwhich the following is a specification.

The main object of our invention is to so Io construct a mold forglassware'as to facilitate the manipulation of the mold and the moldingand removal of the glass, to permit the interchange of dies therein, toreduce the weight of metal required in the mold itself,

I3 and to lessen its cost.

In the accompanying drawings, Figure l is a perspective view of ourimproved glass-mold. Fig. 2 is a transverse section on the line l 2,Fig. 3. Fig. 3 is a longitudinal section on the line 3 i, Fig. 3. Fig. 4is a sectional plan view on the line 5 6, Fig. 3; and Fig. 5 is alongitudinal section of a modification of our invention.

A is the bed-plate of the apparatus supported on suitable legs a a,secured thereto by bolts or other suitable fastenings. In the face ofthis bed are two undercut grooves l) l), to which are adapted the basesof two sliding frames B B, which carry the dies.

Projecting downwardly from the center of the base-plate A is a bearing Dfor the plunger E, which carries the bottom die F, as describedhereinafter. On the bearing D is an external screw-thread, to which isadapted a screw-thread on a hand-wheel G, connected to the plunger E, inthe present instance, through the medium ot a plate e and bolts g, sothat as the wheel is turned the plunger will be raised or lowered forthe purpose of fitting the lower die snugly to the side dies.

The two sliding frames B B have vertical brackets or extensions B', towhich the side dies H H of the mold are secured. These side dies arerectangular in form and have their back portions grooved, forming twobearings 7L h, which it neatly against the vertical brackets B. In thepresent instance we have may be used in their stead.

surface of each slide, as shown in Fig. l, is a rack I, which engageswith a pinion .I on a vertical shaft J Each shaft is provided with asuitable hand-wheel K at aheight convenient. to be operated by theattendant. The shafts J are adapted to bearings j, secured to the bed ofthe machine, and they also have a bearing in the base of the machineitself. By turning the hand-wheels K in one direction the dies are drawntoward each other, and when turned in the opposite direction the diesare separated from each other.

To prevent the dies from passing over the center when moved toward it,we provide each slide with pins 7o k, which engage with stops K',adjustably secured to the base of the machine. These stops can beadjusted for dies of different thicknesses, as will be readilyunderstood.

The dies H H rest upon suitable brackets L L, so that one screw for eachbracket is only necessary to fasten the dies firmly to the slides.

The bottom die F is loose on the head E of the plunger E, which has inits face a groove e', to which is adapted a pin f. The bottom die F hasalso a small central extension f2, which rests in an orifice in the headE. This lower die does not fit snuglyin the head, but has a slight play,so that when the dies H H come together the lower die will seat itself,making a snug fit.

By having the mold part on a horizontal line, as shown and described,the dies can be readily removed f rom the machine and other dies placediu their stead, or, as is often the case, where in druggists bottles aname is required on one half of the die, that half can be removed andreplaced with a die having another name without duplicating the entiremold. The longitudinal sliding dies retreat from the molded bottle moreequally and directly than in a pivoted mold, and by their movement in aright line, instead of around a pivot, allow of panels and recessesbeing made in the sides of blown or pressed articles with sides havingless bevel. Furthermore, by this construction expensive parts andfittings are dispensed with and the weight of metal required in ordinarymolds decreased.

In Fig. 5 we have shown a modification in IOO which the racks are ontheunder side of the Slide B and are Worked from transverse shafts M,which have their bearing in the base of the machine.

The hand-Wheels may be connected together by a strap N, Fig. 5, whenfound necessary, so that when onewheel is turned to open themold theother wheel is turned also .through the medium of the strap, and .when

the other Wheel is moved to bring its mold to Within convenient reach ofthe attendant, substantially as specified.

3. The combination of the sliding frames having die-supporting bracketsL secured thereto, With dies H, resting upon said brackets, and securingdevices by which the dies are attached to the sliding frames,substantially as described. l

el. The combination of the sliding frames carrying dies, each framebeing provided With pins k, With adjustable stops K on the base, againstwhich the pins strike when the dies are at the limit of their inwardmovement, substantially as set forth.

In testimonywhereof We have signed our names to this specification inthe presence of two subscribing Witnesses.
